An apparatus for connecting a cover to a chock in a rolling mill comprising spaced supports on the chock, an arm extending laterally from the cover into the space between the supports, and a pin extending through communicating openings in the supports and the arm. Certain of the openings are dimensioned in relation to the pin to accommodate axial shifting of the cover between a closed position against the chock and an intermediate position from which the cover is free to pivot about the pin to an open position exposing the bearing end. A disengageable retainer is provided for holding the cover in the closed position. |
